Wiring

Cut the harness of the oxygen sensor.

See colors operations of each wire in Snowmobile wiring diagram or search for your combination in the table below.

Connect the proper wires with terminals or solder them in place. (Hydrochloric acid recommended if soldering.)

Contact the red cable of the red/black dual wire to the ignition feed + 12V, and the black to the engine frame or battery negative.

Mount the unit to any fixture as far from heat as possible. Lowest temp recommended.

No heater test required in case of 2-wire sensors.

Heater adjustment

Heater adjustment is required if heater related CEL code is tripped after installation. This is not uncommon.

Heater dial can be determined with an Amper-test.

Take a multi-meter and turn it to AMP mode.

Contact the stock sensor's one wire to the battery negative terminal, the red lead of multi-meter to the battery positive and black lead to the other heater wire.

Wait 10 seconds until heater warms up (cold and hot amp readings differ) and check the AMP reading. Take note of it.

Repeat the same test with the simulator and set the same AMP reading by dialing screw#2. Wire up simulator’s heater wires to the vehicle’s heater harness afterwards.

Working Theory

Magnum Snowmobile Oxygen Sensor Simulator is a must-have tuning upgrade if you installed aftermarket pipe, or heavily souped-up the exhaust in any way, on your emissions-controlled SLED. The modified motor now produces a larger amount of exhaust gases than allowed. When the exhaust gas oxygen sensor delivers the ECU a signal that is not within the manufacturer's specifications the OBD-II (OnBoard Diagnostic) system logs an error, accordingly CEL will illuminate, resulting in PCM limp mode and reduced performance potential. Heated Snowmobile Polaris 800 Switchback PRO-X O2 Sensor Simulator is an add-on replacement hooked up to the post exhaust o2 sensor harness. It supplies the Electronic Control Unit with mimic, fluctuating voltage signal and overrides the Power Control Module thinking the emission is normal. This Polaris 800 Switchback PRO-Xoxygen sensor simulator will allow you to run with your exhaust piggybacks and still keep the MIL light off.

Note

This SLED Oxygen sensor simulator is a racing part. It is not CARB approved. Please be aware of the bylaws and regulations, O2 sensor eliminator is not legal in several US states and countries.

Questions and answers

Can I be positive this chip fixes my CEL issue for good?

Yes, Magnum oxygen sensor simulator produces a random fluctuation having assigned with suitable cycle and wave accepted by the ECU. Rest assured, all oxygen sensor related codes will be gone.

What if I simply eliminate factory oxygen sensor?

Oxygen sensor removal will not remedy CEL issue. Suitable fluctuating signal is fundamental to be delivered by the ECU. Zero volt signal triggers another trouble code

Why is it so important to cancel the trouble code?

While check engine light is on, ECU restricts the engine performance and vehicle is running in safe / limp mode. MPG is also affected negatively.

What about 'oxygen sensor bungs' 'mini cats' or any other piggybacks are also supposed to sort our FI problems?

The market is teeming with physical gadgets aiming to fix CEL issues. Vast majority of them often don't work on Snowmobiles.

Get rid of oxygen sensor related CEL issue yet today. Injected gasoline engines controlled by Electronic Control Unit (ECU) or alias Electronic Control Management (ECM) have oxygen sensor or O2 sensors to measure the amount of oxygen contained in the exhaust gas. These sensors deliver the ECU fluctuating voltage according to the actual oxygen consistence of air fuel mixture. When exhaust system is decatted or heavily modified, ECU is reading an oxygen sensor signal being inconsistent with other engine sensor's signal, or signal is out of the range yet accepted, an O2 sensor-related trouble code will be triggered ending up in check engine light issue. CEL or MIL or FI errors abbreviate these failures. While check engine light is on, ECU runs in so called lean limp mode. Safe mode restricts both the fuel trim and the ignition timing and develops an overall limitation on performance, until problem diagnosed and resolved definitely. Therefore if you modified your engine with any upgrade causes the oxygen sensor deliver lower signal than normally, you need to wire up an Oxygen Sensor Simulator. Although your ECU will be tweaked, mixture's air fuel ratio still will remain incorrect hence decatting or any other exhaust modification. Simulators help you remedy CEL problems but will not achieve that basic remapping is crucial when modifying an exhaust. You might be interested in our further performance chips in order to boost engine horsepower, improve fuel efficiency or both at the same time. EVO-Tech, Dyno-Boost and Smart-Tune-X fuel controller remap the ECU in order to reprogram the engine management to the performance parts preinstalled on the vehicle. They boost the engine horsepower as well as improve fuel mileage. Magnum Tuning has been dealing with manufacture of performance upgrades since 1994.

Although Magnum O2 Sensor Simulator makes you enable to adjust the air fuel ratio within a certain range, basically it is not intended to remap the fuel trim. If you are about to override the factory lean fuel programming or you want to optimize the potential of your exhaust upgrade, feel free to check out our fuel controllers .

Oxygen sensor eliminator has to be powered on ignition feed DC 12V. Never connect hot wire to constant battery voltage. This wiring may lead to battery drainage also may fry the circuit.

Smog test result depends on the criteria of your local emissions inspection. Simulator is neither supposed to improve emissions spoiled by an aftermarket pipe or any other upgrade, nor restore factory emissions required for a smog inspection. It is solely intended to help you get rid of ECU safe mode triggered by check engine light issue. It will not allow you to preserve factory emissions level. Simulator tricks the computer delivering mimicked signal is accepted by the ECU but it can’t purify the fume electronically. Cat is intended to attain that physically. Even though restoring of ECU to normal mode from safe mode improves emissions partially, if converter is gutted, worn or defective, original emissions can be preserved by no means.

The simulator is waterproof but not submersible.

Oxygen sensor simulator's signal is set to factory 0.9…0.95V top voltage. Don't adjust signal related screw#1 until CEL issue is resolved. Basically screw#1 should not be dialed unless you want to modify air fuel ratio. We don't bear responsibility for CEL shut down, if signal is not set to the top voltage above.

product shipped quickly. When opened up the package i discovered this is not a plug and play eliminator i was chasing after but because i had a race at weekend and compliance test was on due i had to swallow the bitter pill trying to conceal the terminals and the tap-in. factory perfection took a hit, before i was averse of splicing into the stock wiring loom. By necessity hence aftermarket pipe i had to shut down my cell to pass the rigorous emission and readiness test. The o2 elimintor worked as said and i am grateful but not delighted with the install method. Bear in mind you need to slash oxygen sensor wires.

simulator is not carb approved

I guess it would put a dent in sales if they put on the box this oxygen sensor simulator is not carb approved. Although it does what ad suggests to do, the company should tell you, you are not permitted to install an eliminator as long as you are so sucker you want to comply with emission by-laws.

this o2 sensor delete seems to be a universal fit eliminator applicable to trucks, bikes and sleds, they still advertize it straight to my sled. All in all it helped me get rid of engine code popped up rite after my (removed) slip-on exhaust was instaled. Service is good but I have to duck one star due to inadequate wiring instructions.

I recommend but I have to duck one star

o2 sensor bypass worked fine but after 2 months in the line of duty it stopped to work, repalcement was a bit fussy, they insisted on returning the product for warranty diagnosis that took time and cost money, true enough replacement was sent on the other day, I recommend but I have to duck one star due to unexpected overlay.

My sled felt like choking after (removed) pipe installed but after scanning the cdi it still run lean. this o2 sensor bypass sorted out the oxygen sensor failure code made the sled turn to safe mode. Sled runs like new, responds like new.
